Image Type Conversion

Convert between the image types, such as RGB (truecolor),
binary, grayscale, and indexed.

Image Processing
Toolbox™ supports binary, indexed, grayscale, and truecolor
image types. In each image type, pixels are
stored in different formats. For example, truecolor images represent a
pixel as a triplet of red, green, and blue values, whereas grayscale
image represent a pixel as a single intensity value. Pixels value can be
stored in floating-point, signed and unsigned integers, or logical
data types. Toolbox functions enable you to
convert between the image types and data types.
